Various embodiments of the teachings herein include a battery unit comprising a string of battery modules in series. Each battery module includes a plurality of battery cells in series. Each battery module comprises a respective balancing circuit and a respective power electronics unit with a first DC/DC converter. The respective battery modules are connected in series via the respective power electronics unit. In each battery module, the first DC/DC converter comprises: an input port with two input terminals connected to the battery cells; an output port with two output terminals providing an output voltage; and a power supply port receiving power for the first DC/DC converter from the balancing circuit. The first DC/DC converter sets the output voltage of the battery module to a predetermined value. The balancing circuit extracts energy from a selected battery cells and provides it to the first DC/DC converter or the power electronics unit.
